Sigh. I tried.

These sprockets are in no way faulty, we absolutely abused them beyond reasonable, with chain tension so high the chain actually made a "sproing" sound when plucked, no lubrication at all on dirty, used chain, and a very small diameter (15T) coming off the ball shifter (very high power transmission with about 90 degrees of wrap).

On Team 1676, the adult mentors advise and sometimes cajole, but we don't overrule a student decision (except for safety). Maybe there's some education that happened here. Finally.

sheesh.

Truth.

The chain should move up and down a distance proportional to the length of the chain.
